EXTENSIBLE GRILLE.

Application led April 16, 1928. Serial No. 270,314.

rlhis invention relates to an extensible grille, and has for its objectto prov1de a metallic grille of such construction that 1t may be readilyapplied to fill a part of the area between upright supports as a guardor barrier, and may be used to advantageupon screen doors or upon theframes of window screens.

It is well known that, on account of their' exposed position, thescreens upon screen doors often become injured and detached or loosenedfrom the frames. The grille to be described herein may be convenientlyapplied to screen doors of various widths and will adequately resist allstresses directed thereto and will prevent injury to the screen.

The new and useful features of the invention are fully described hereinand illustrated in the accompanying drawing, it being understood thatchanges may be made in form, size, proportion of parts and minordetails, said changes being within the scope of the invention asclaimed.

In the drawing Fig. 1 is a view in side ele vation of a part of a screendoor and door frame, with the grille applied thereto. Fig. 2 is a sideview of an extensible supportingstrip. Fig. 3 is a view, partly insection, showing a part of one of the tubular, telescopinggrille-supports.

Referring now to the drawing for a more particular description, theinvention is shown and described in connection with a screen door framed hinged to a door casing 5, and consists, in part, of a rectangularframe including a pair of side strips 6 which are secured at their endsto an upper extensible support 7, and to a lower extensible support 8.

Each support 7 and 8 consists of a metallic tube or sleeve 9 provided atits ends with secondary sleeves or tubes 10 adapted to have slidingmovements in a tube 9 and each provided with a foot-piece 11 adapted tobe secured to the frame of the screen door.

Numeral 12 indicates a plurality of upright parallel metallic strandsuniformly spaced apart each being mounted at its ends upon the tubes 9,said mountings being by means of terminal loops 13, the ends of thestrands being bent to form said loops 15.

Numerals 16 and 17 respectively indicate pairs of opposedsupporting-strips, each being provided with a foot-piece 18 for amounting upon the frame of the screen door as shown in the drawings.However wire may be used if desired. They are interwoven, that is to saythe opposed sides of the strands 12 are engaged in alternation by thestrands 141. Also the opposed sides of the supporting strips 16 and 17are engaged in alternation by the vertical strips 12.

As thus described it will be seen that the grille may be readily mountedupon the door frames of various widths. The secondary or inner tubes 1()may be drawn outwardly from the tubes 9, the pairs of supporting-strips16 and 17 being also drawn outwardly from the grille so that thefoot-pieces 11 and 18 will engage the door frame t and may be securedthereto, the function discharged by the horizontal strips 16' and 17being to support the web or grille betweenits top and bottom.

1t will be appreciated that the device consists of few and simple partsand therefore may be manufactured economically. Also on account of theconstruction as described the grille will be adequately supported andbending or buckling of the strands, which might be caused by shocks orundue pressure, will be adequately resisted.

I claim as my invention 1. A grille for door and window frames,comprising an open mesh panel portion, spaced apart supports on thepanel portion for attachment to a frame, and independent reinforcingstrips for attachment at one end to the fiame and adapted forintermeshing engagement at their other ends in said panel portion tosteady the saine between said supports.

Q. A grille for door and Window frames, comprising spaced apartsupporting bars,

spaced apart side strips attached to said bars and forming therewith asubstantially rectangular frame, interwoven spaced apart strands of wiresecured to said bars and to said side strips thereby forming an openmesh panel, said supporting bars extending beyond the side strips forattachment to a frame, and separate and independent reinforcing stripsbetween said bars adapted to be secured at one end to the frame and tothreadingly engage the mesh panel at their other ends therebyreinforcing and stabilizing the panel.

In testimony whereof, I have atlixed my signature.
